Early Flash


By igniting magnesium in a globe of pressurised oxygen, Frenchman Chauffour designed the first photoflash bulb. The device functioned by sealing a magnesium wire inside a glass jar with oxygen. The magnesium would ignite through a wire transmitting an electric discharge. It was meant to aid Louis Boutan in his experiments with underwater photography. In 1930 General Electric launched the first commercially available flashbulb, the Sashalite. It made use of an aluminium foil in a pure oxygen surrounding.
